Diploicia canescens (Dicks.) A. Massal.
Ric. Auton. Lich. Crost.: 86, 1852. Basionym: Lichen canescens Dicks. - Fasc. Pl. Cryptog. Brit., 1: 10, 1785.
Synonyms: Buellia canescens (Dicks.) De Not.; Catolechia canescens (Dicks.) Anzi; Lecidea canescens (Dicks.) Ach.; Placodium canescens (Dicks.) DC.
Description: Thallus crustose-placodioid, glaucous grey but usually densely white-pruinose, forming 1-4(-6) cm wide, usually orbicular rosettes, sometimes several thalli merging and covering larger surfaces. Lobes radiating from the center, 0.5-1.2 mm wide, contiguous, slightly convex, rounded and often slightly broader and fan-shaped at ends, with laminal, at first orbicular soralia developing from small bulges, finally bursting and irregular; soredia finely granular, greenish white to grey; lower surface usually pale, attached by medullary hyphae. Upper cortex pseudoparenchymatous, formed by vertically arranged hyphae, filled with minute crystals forming chains in K; medulla usually white, lax. Apothecia rare, lecideine, black, up to 1 mm across, laminal. Proper exciple thin, dark brown to black; epithecium granular, brown-black, K-; hymenium colourless, I+ blue; paraphyses simple or forked, the apical cells swollen, with a dark cap; hypothecium brown or brown-black. Asci 8-spored, cylindrical-clavate, the apical dome K/I+ dark blue with a pale, conical-pointed apical cushion (axial mass), the wall I-, but the thin outer gel I+ blue, Bacidia-type. Ascospores 1-septate, grey green to brown, thick-walled, ellipsoid, 9-15 x 4-8 µm Dirinaria-type, with ontogeny of type B (apical inner wall-thickenings produced before septum formation). Pycnidia immersed, brown-black, the wall dark near the ostiole, otherwise colourless, the conidiogenous cells enteroblastic, pleurogenous, branched. Conidia hyaline, short-bacilliform, 5-8 µm x 0.7-1 µm. Photobiont chlorococcoid. Spot tests: cortex K+ yellow, C- or C+ pale pinkish yellow, KC+ brownish yellow or yellow-orange, P- or P+ yellow; medulla K-, C-, KC-, P-, UV+ dull orange. Chemistry: cortex with atranorin and often chloroatranorin, medulla with dechlorodiploicin (minor), isofulgidin (minor), dechloro-O-methyldiploicin (minor or trace), buellolide (minor), canesolide (minor or trace), and secalonic acids A, B and C (minor or trace).
Growth form: Crustose placodiomorph
Substrata: bark and rocks
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
In underhangs rarely wetted by rain
